“…Although adequate bond strength can be achieved with surface treatments, oral environment with pH, temperature changes and use of various chemicals for cleaning and disinfecting dentures further diminish bond strength and can cause bond failure eventually 20. Therefore, disinfectants with little or no effect to the bonding properties of resilient liners to the acrylic are important for long term clinical use.…”

PURPOSEThe aim of this study was to evaluate the effect of paracetic acid (PAA) and ozone disinfection on the tensile bond strength (TBS) of silicone-based resilient liners to acrylic resins.MATERIALS AND METHODSOne hundred and twenty dumbbell shaped heat-polymerized acrylic resins were prepared. From the mid segment of the specimens, 3 mm of acrylic were grinded off and separated parts were reattached by resilient liners. The specimens were divided into 2 control (control1, control7) and 4 test groups of PAA and ozone disinfection (PAA1, PAA7, ozone1 and ozone7; n=10). While control groups were immersed in distilled water for 10 min (control1) and 7 days (control7), test groups were subjected to PAA (16 g/L) or ozone rich water (4 mg/L) for 1 cycle (10 min for PAA and 60 min for ozone) per day for 7 days prior to tensile tests. Measurements of the TBS were analyzed using 3-way ANOVA and Tukey's HSD test.RESULTSAdhesive strength of Mollosil decreased significantly by application of ozone disinfection. PAA disinfection had no negative effect on the TBS values of Mollosil and Molloplast B to acrylic resin. Single application of ozone disinfection did not have any negative effect on TBS values of Molloplast B, but prolonged exposure to ozone decreased its adhesive strength.CONCLUSIONThe adhesion of resilient liners to acrylic was not adversely affected by PAA disinfection. Immersion in ozonated water significantly decreased TBS of Mollosil. Prolonged exposure to ozone negatively affects adhesion of Molloplast B to denture base materials.

This study aim to investigate the effect of denture cleansers and standblasting on tensile bond strength of soft denture liners after 3 and 6 mounths of immersion.For each of the liner materials, 70 test specimens were prepared according to test the requirements. Half of the 70 test specimens were sandblasted with 50 μm Al2O3 at 2 bar for 10 s. The resilient liner specimens were processed between 2 polymethyl methacrylate (PMMA) blocks. Before tensile testing, five of the liner specimens were kept in water or soaked in two cleansing solutions during 3 and 6 month. Bonding strength of the liners to PMMA was compared by tensile test with the use of universal testing machine at a crosshead speed of 50 mm/min. The mean value and standard deviation of the specimens were made by using a multifactorial analysis of variance (α=0.05). The type of failure was assessed visually.No significant difference was found between the groups for the tested conditions used (p>0.05). The most frequent failure mode was cohesive for Permaflex (P) specimens, adhesive for sandblasting groups, and a mixed type of failure was observed for GC Reline Soft (GC) material.The denture base cleaners affect the bond strength of PMMA/resilient liner. Permaflex and GC Reline Soft as resilient liners were found to have adequate adhesive values for clinical use.

“…A main drawback associated with the use silicone liners, however, is their higher propensity to bond failure, because silicone has a structurally different chemistry when compared with PMMA denture base resin [7,10,[15][16][17]. Clinically, although complete separation does not always occur, local areas of separation between the liner and the base may become unhygienic because of the difficulty of cleaning between the two materials [9,18,19].…”

This study evaluated the effect of argon plasma treatment on tensile bonding of heat-cured and auto-polymerized acrylic resins prior to the processing of a silicone soft liner. Both types of polymethylmethacrylate (PMMA) resins were treated with argon plasma for 1 min or 10 min (n ¼ 5). A control group, including untreated resin specimens, was also formed. After processing of the soft liner, the specimens were deflasked and stored dry for 24 h, and they were then subjected to tensile bond strength testing. In order to see the plasma effect on the resin surface chemistry, representative specimens were analysed by XPS. Highest tensile bond strengths were observed in the 1-min exposure group for each resin, and 10-min exposure yielded the lowest bond strength likely due to the damaging effect of the plasma treatment. XPS analysis showed that the O=C ratios increased greatly in treated samples and that the binding energy values were not significantly changed.
